want to know what “begging the question” means?

Here you go:

So most likely when Trump refers to “the media” as the most dishonest people on the planet, he refers only to professional journalists. This is a contradiction in terms, because modern journalism is a profession predicated on conveying truth. Journalists’ currency is credibility. To quibble with a particular journalist’s motives is to quibble with their identity: Are they journalists? Or entertainers, ideologues, or advocates?

The goal in journalism is to be the best at identifying and conveying said truth. The entire concept of the profession is antithetical to lying. So it’s difficult to imagine objecting to the idea of journalism, in principle: To have people whose job is to act as dispassionate arbiters who discern truth. People who are fair, who are trustworthy, who do not slander, who are not beholden to any particular interest but seek transparency, to highlight injustice, and to hold people in power accountable.

James Hamblin. I’ve never seen such a laboratory-pure case. To the charge that journalists care more about pursuing political ends than telling the truth, Hamblin replies that that’s not possible because journalists are intrinsically and necessarily people who care about telling the truth more than political ends. Quod est demonstrandum.
